Made with Aomori Hiba cypress and cork! The stainless steel wire is doubled for durability and twisted tightly so it won't spin around. It's stable! Please adjust the hanging position yourself. For safety, the top part is wrapped with hemp twine and secured with zip ties. The bottom is designed for pulling and playing. Paper yarn seems to be a recent favorite, so I used it! It's intentionally cut roughly to make it easier to rub against with their beaks. (σ゜Д゜)σ This will help them grind down long beaks! Length: Approximately 18cm-20cm Width: Approximately 4cm-5cm
